Pengaruh Ekstrak Etanol pada Tomat (Solanum lycopersicum L.) pada Staphylococcus epidermidis secara in Vitro

Tomato is one of the plants that contain lycopene as an antibacterial. Acne is an infectious disease caused by Staphylococcus epidermidis. Antibiotic treatment starts to become resistant so that plants can be used as alternative treatments. The study aimed to determine the effectiveness of the ethanolic extract of tomato (Solanum lycopersicum L) against the growth of Staphylococcus epidermidis bacteria in vitro. This type of research is experimental. Extraction was carried out by maceration method with 96% ethanol as solvent. Lycopene extract with concentrations of 20%, 40%, 60%, 80%, and 100%. Testing with the paper disk method with five repetitions. Aquadest as a negative control, and tetracycline as a positive control. The results showed that the diameter of the inhibition zone formed in the positive control was 40.36 mm (potent inhibition). Inhibition zones at concentrations of 100%, 80%, 60%, 40%, and 20% had solid inhibitory power. The results of statistical tests showed that the ethanolic extract of tomato (Solanum lycopersycom L) had antibacterial effectiveness against the growth of Staphylococcus epidermidis bacteria that causes acne in vitro. The post hoc test shows a significant effect between a T1 concentration of 100% with negative control and positive controlBuah tomat merupakan salah satu tanaman yang mengandung likopen sebagai antibakteri. Jerawat merupakan penyakit infeksi yang disebabkan oleh Staphylococus epidermidis. Pengobatan dengan antibiotik mulai resistensi, sehingga tanaman dapat dijadikan sebagai alternatif pengobatan. Penelitian bertujuan untuk mengetahui efektivitas ekstrak etanol pada buah tomat (Solanum lycopersicum L) terhadap pertumbuhan bakteri Staphylococcus epidermidis. Penelitian berjenis eksperimental. Ekstraksi dilakukan dengan metode maserasi dengan pelarut etanol 96%. Ekstrak likopen dengan konsentrasi 20%, 40%, 60%, 80% dan 100%. Pengujian dengan metode paper disk dengan 5 kali pengulangan. Aquadest sebagai kontrol negatif dan tetrasiklin sebagai kontrol positif. Hasil penelitian menunjukkan diameter zona hambat yang terbentuk pada kontrol positif adalah 40,36 mm (daya hambat kuat). Zona hambat pada konsentrasi 100%, 80%, 60%, 40%, 20% mempunyai daya hambat kuat. Hasil uji statistik menunjukkan bahwa ekstrak etanol pada buah tomat (Solanum lycopersycom L) memiliki efektivitas antibakteri terhadap pertumbuhan bakteri Staphylococcs epidermidis penyebab jerawat secara in vitro. Pada uji post hoc bahwa terdapat pengaruh yang signifikan antara T1 konsentrasi 100% dengan kontrol negatif dan kontrol positi

Prospek Model Daur Belajar 5 Fase terhadap Keterampilan Proses Sains dan Kemampuan Berpikir Kritis Siswa pada Materi Termokimia

Materi termokimia mencakup konsep-konsep yang bersifat abstrak, algoritmik, dan saling berhubungan satu sama lain sehingga siswa mengalami kesulitan dalam memahaminya. Selain itu, proses pembelajaran kimia selama ini cenderung menggunakan model pembelajaran konvensional. Model pembelajaran ini lebih menekankan pada hasil belajar kognitif, namun tidak memperhatikan aktifitas keterampilan proses sains dan kurang melatih kemampuan berpikir kritis siswa. Dengan demikian, diperlukan model pembelajaran yang mampu meningkatkan keterampilan proses sains dan kemampuan berpikir kritis siswa yaitu menggunakan model daur belajar 5 fase. Kajian ini bersifat deskriptif dan berbasis literatur yang bertujuan untuk mengetahui prospek model daur belajar 5 fase terhadap keterampilan proses sains dan kemampuan berpikir kritis siswa

Empowering public health awareness through dissemination of traditional medicine products

Traditional medicines have been an integral part of the cultural heritage and health systems of various societies around the world. To promote the use of traditional medicine and understand it more deeply, the dissemination of traditional medicine products is a crucial step. The purpose of this service is to explore the importance of the dissemination of traditional medicinal products and their benefits to the community.  The main target of this activity were people who have a history of chronic disease. In addition, public awareness to obtain information related to traditional medicine products was still lacking. The method of implementing this service activity was carried out by providing direct education related to traditional medicine to the community. As a result of the service, 19 traditional medicine products were disseminated and increased public awareness about traditional medicine. This result implies that the use of traditional medicine should be widely encouraged to a larger community
